25 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Hazard
- A source or situation with potential to cause harm, considered separately from the likelihood and consequences of a particular exposure.
- Risk assessment
- A structured examination of what can go wrong, who can be affected and how existing or proposed controls change the outcome.
- Exposure pathway
- A connection by which an agent can move from a source to a person or other receptor under defined conditions.
- Elimination
- Removing a hazard or the need for the hazardous activity rather than relying only on behavior during the task.
- Substitution
- Replacing a material or process with another option while assessing the new option for its own hazards and limitations.
- Engineering control
- A physical or technical measure intended to reduce exposure or prevent a hazardous event through the design of work.
- Administrative control
- A planned work arrangement, instruction or scheduling measure that depends on implementation and does not physically remove every hazard.
- Personal protective equipment
- Equipment selected to reduce specified exposure or injury risks within an appropriate assessment, maintenance and use process.
- Residual risk
- Risk remaining after selected controls are considered under the conditions and assumptions required for their effectiveness.
- Common-cause failure
- A condition capable of defeating more than one nominal barrier, limiting the claim that those protections are independent.
- Near miss
- An event without the reported injury or loss outcome that can nevertheless reveal a credible hazard or failed barrier.
- Safety culture
- Shared assumptions and behavior concerning safety that should be examined through actual decisions, reporting and control performance.
- Time-weighted average
- An average calculated by weighting concentrations or other measurements by their corresponding durations over a defined period.
- Detection limit
- A method capability relevant to interpreting a reported result, not proof that every unreported substance is absent.
- Breathing-zone sample
- A sample intended to represent air near the worker respiratory intake over the stated method and sampling period.
- Particulate filter
- A component intended to capture particles within its approved performance, without automatically removing gases or supplying oxygen.
- Decontamination
- An assessed process for removing or reducing contamination while preventing transfer to people, clean areas or other equipment.
- Containment
- Measures intended to limit migration of contamination or a hazardous condition within a defined and managed work area.
- Clearance
- A specified post-work acceptance process whose methods, roles and criteria depend on the applicable project and governing program.
- Incident investigation
- Examination of an event and the conditions behind it to identify effective corrective action rather than only assign personal blame.
- Fit test
- An evaluation of whether a particular tight-fitting respirator model and size provides an appropriate seal on the wearer.
- Competence
- Demonstrated ability to perform a defined task under the relevant conditions, rather than attendance at a learning activity alone.
- Emergency plan
- An arrangement defining communication, roles and appropriate actions for foreseeable emergencies within the actual site and resources.
- Manual-handling assessment
- Evaluation of a handling task considering the load, activity, person, environment and ways to reduce the need for hazardous movement.
- Control verification
- Checking that an intended protective measure is present, suitable and effective under the actual conditions of the task.
